Patent GB-1451688-A (GB)
Title: Automatic shutoff mechanism for magnetic tape recording and reproducing apparatus
IPC: G11B15/22
Filed: 1974-08-05
Abstract: 1451688 Tape recorders SONY CORP 5 Aug 1974 34439/74 Heading G5R A reel-to-reel tape recorder includes means driven by the reel-drive motor for stopping the motor when the reels stop rotating, e.g. at the completion of tape winding from one reel to the other. As shown, during operation of a cassette recorder otherwise similar to that described in Specification 1451680 a lever 190 is oscillated by a rotating cam 252 but is limited in its anticlockwise stroke by the engagement of a pin 236 with a stop 248 or 250 in a plate 212 which is urged to one side or the other by a rotating reelsupport 23 through a friction clutch 218. On full winding or unwinding of the tape the reel-support 23 is stopped, and in its next oscillation the pin 236 enters the centrally located recess 242B, allowing the lever 190 to complete its anticlockwise stroke and engage a lug 200, swinging a gear wheel 180 into engagement with a rotating gear 188. This causes a sector gear 184 to be driven anti-clockwise, Fig. 7D, so that an end 166 of a latch-release member 162 carrying the sector gear 184 pushes a depending leg 168 of a latch 48, releasing any operated control push-button and stopping the recorder. However, this automatic shut-off is disabled during the review made of operation, when the rewind button is pressed while the play button is operative, Fig. 8 (not shown).

Title: Improved apparatus for erecting boxes from blanks
Inventor: AGAR ROBERT LESLIE
IPC: B31B3/44
Filed: 1962-09-08
Abstract: 978,906. Plunger and die mechanism. MARDON, SON & HALL Ltd. Aug. 27, 1963 [Sept. 8, 1962], No. 34461/62. Heading B5D. A plunger and die mechanism of the type comprising a series of plungers mounted on a conveyer which moves in synchronism with another conveyer upon which are at least partly mounted a series of dies is characterized in that each die comprises a pair of forming elements which co-operate with fixed rails as the forming elements move along a straight line between said rails to bend up the sides of a blank. The lowermost blank 50 of a stack 86 is delivered to a conveyer 87 by raising pipes 68 and applying suction therethrough to pads 80, 81 at the upper ends of the pipes, both actions being effected by cam means. Pushers 88 on conveyer 87 then carry the blank to another conveyer 62 where further pushers 63 deliver the blank to a pair of forming elements 72, 73. Each pair of forming elements are mounted on an endless chain conveyer 8, slide on rails 32, 33, and are provided with lugs 43 to correctly position a blank 50 delivered thereto. A plunger 34 is mounted above each pair of forming elements 31 on a pair of chains 12, 13 which move in synchronism with the conveyer 8 and is lowered into the die formed by a pair of forming elements and the rails 32, 33 by means of a cam follower carried at the upper end of the plunger which engages in a cam track 37 formed by rails 40, 41. The plunger is then retracted out of the die as the cam follower moves up a sloping portion 52 of the cam track and the box is removed when it passes a sloping rail 53. In the case of lidded boxes, pins 44 are secured to a conveyer chain 9 moving parallel to and synchronously with the conveyer 8 to maintain the blanks horizontal. The blank comprises interlocking tongues and slots and the forming elements are shaped in such a manner as to cause said interlocking to take place. If the box has overlapping parts to be heat-sealed together a radio-frequency generator 92 is connected to the machine, the live and earthed electrodes comprising the rails 32, 33 and the plunger heads 38 respectively. The radio-frequency field set up thereby effects the heat-sealing.

Starting materials.  The thiol esters which are used as starting materials are made by reacting an acylated a -amino acid, such as acetylmethionine, with an acid chloride (e.g. isovaleric acid chloride) to give a mixed anhydride, which is reacted with the thiol compound (e.g. thiophenol or thioglycolic acid) to give the appropriate thiol ester such as the thiophenyl esters of dl acetyl-methionine, aceturic acid and dl-acetyl-b -phenyl-alanine and the thioglycolic acid ester of dl-acetyl-methionine. Specification 735,685 is referred to.

Title: Selvedges in woven fabrics
IPC: D03D47/44
Filed: 1976-08-20
Abstract: On the side facing away from the weft-insertion side, the fabric (11) has a selvedge, on which a first catch thread (8) retains the inserted weft-thread loops and a second catch thread (9) prevents a loosening of the first catch thread (8). The first catch thread (8) is drawn through each successively inserted weft-thread loop, in order to form a first series of stitches. The second catch thread (9) is drawn only through selected stitches of the first catch thread (8), in order to form a second series of stitches simultaneously with the selected stitches of the first catch thread (8). The second series of stitches can be produced with any stitch or with alternating stitches of the first catch thread (8). The first and the second catch thread (8 and 9) are guided through guide members (6 and 7), the first guide members (6) being moved, whenever the weft-inserting needle (1) is moved to insert a weft-thread loop, into a position in which they guide the first catch thread (8) into the path of movement of the insertion needle (1). <IMAGE>
